BRAKE-GEAR HOUSING.

Application filed April 10, 192G. Serial No. 101,158.

"My invention relates to a gear housing adapted to be secured to the end sill ota car underframe, comprising a two piece member so constructedas to provide a hous- 6 ing possessing strength and rigidity; wherein assembly of the gear elements may be readily accomplished, and whereby attaclr ment to a car underframe member may be easily made.

My invention and its objects will be readily comprehended from the detailed description of the accompanying drawings, wherein v Figure 1 is atop plan view of my 1m- 16 proved housing shown attached to the end sill of a car underframe, a portion of the end sill being shown in section.

Figure 2 is a transverse section taken sub stantially on the line 2-2 of Figure 1.

.20 Figure 3 is a perspective view of the bottom member of the housing.

Figure 4 is an end elevation of the housing and gear elements therein, looking at the outer end of the housing and outer face of the end'sill. l

Figure 5 is a perspective view of the top member of the housing. a

Figure 6 is a side elevation of the housing with the gear elements and brake-staff omit- :m ted; the end sill being shown in section.

My invention, as exemplified inthe drawings, comprises a housing composed of two members, consisting of a topvmember 10, see Figure 5, the main portion whereof is practically of rectangular configuration, see Figure 1, and is adapted to be secured to the lower flange of the end sill member 11 of the car underframe so as to be disposed transversely 'therebeneath. The main body or- 4 tion, intermediate of its ends, is provided i with laterally disposed lobes 12, 12 apertured to permit being riveted or, otherwise secured to the lower flange of the end sill as shown at 13. The forward or outer end of the topmember 10 of the housing, namely forward, of the lobes 12, 12, is provided with depending sides or portions 14, 14

adapted to be disposed at diametrically op-,

posite sides of the drive gear 15 which is controlled by the brake-staff 16. The forward or outer end of the housing is preferably provided with the offset arcuate portion 17 which overlaps thetop ofth-e drive gear 15; this gear 15, like the driven gear 18, is horizontally disposed.

The inner or rear end of the top member 10 is provided with a pair of extensions arranged to extend beyond the plane of the perimeter of the driven gear 18; that is to say, the rear or inner end of the top member 10 adjacent to one longitudinal side is provided with the obliquely disposed extension 19; while the other longitudinal side isprovided with the substantially right angularly disposed extension 20; the extensions 19 and 20 being provided with downwardly disposed ends 21 and 22, respectively.

For purposes of strength, the marginal edges of the top member are preferably flanged, as are also the downwardly disposed ends 21 and 22.

The upper surface of the top member 10, at a the lobes 12, 12 is provided with anupstanding portion or wall 23, which is adapted. to extend flush with the rear side of the end sill 11 and to be attached thereto, by means of the rivets 24- or otherwise. The upstanding portion 23 is reenforced by rearwardly sloping webs 25 and 26; the web 26 being shown extending out toward the end of the extension 19 so as to reenforce the latterland also brace the housing against the pulling strains of the brake-chain; that is to say, the webs 25 and 26 act as compression members whereby any tendency toward upward tilting of the rear end of the housing induced by the pull of the chain will be. transmitted to the rearside of the end sill 11. The top member 10, along the forward 1ongitudinal side of the portion provided with the lobes 12, 12, is preferably provided with a transverse rib 27 which is adapted to come flush with the forward edge of the lower flange of the end sill 11; that is to say, the rib 27 and the upstanding portion 23 are spaced. apart a distance just sufficient to receive the lower flange of the end sill 11 therebetween, as shown in Figures 2 and 6.

The forward end of the top member 10 is provided with a suitable opening to receive the upper end of the hub 28 of the drive gear 15; the hub 28 being also formed to receive a squared port-ionof the brake staff 16 so as to cause the drive gear 15 to rotate with the shaft. The lower end of the hub 28 of the drive gear is preferably flanged inwardly as shown at 29 to provide a pocket forthe end of the brake-staff 16;

point adjacent to the portion having while permitting the reduced cylindrical end 30 of the brake-stali' to be disposed therethrough. The top member a point rearward of the end sill is suitably apertiired to receive one end of hub 31 of the driven gear 18, see Figure 2, the hub on the lower side of the driven gear being extended with 35extendingjflush with the inner sides of the depending ends 14, 14; the depending ends 14 and flanges 35 being apertured to permitthe membersto be readily secured together by means of rivets or otherwise. This forward rectangular portion 3520f the bottom member 33 has a countersunk opening 36 'to receive the lower end oi. the hub 28 of the drive gear 15 and thus provide a shoulder or rest therefor while permitting the reduced lower vend 30 of the brake-start 16'to extend therethrough as shown in Figure 2. The countersunk opening 36 will maintain the drive elements in proper po-, sition when the top and, bottom nember of the housing-are secured together, because the lower'end 29 of the hub28 will rest on the annular shoulder 37 and thus prevent improper movement or play of the drive mechanism. Disposed rearwardly and downwardly from the inner longitudinal edge of the rectangular portion 34 is an arm 38-,which terminates in, the ramifications or portions 39 and 40 which in turn have upwardly disposedcurvingends, as shown in Fi ure 3. The ramification 39 extends outward at'an oblique, angle, and corresponds to the portion 19,01" the top member 10; the end ofthe'ramification being shown 'redu'cediand laps the inner'side of the downwardly disposed'endill of arm 19fand is suitably secured thereto. The ramification 40 extends substantially at right angles, to the arm '38 and corresponds with the arm 20 of the top member; the upwardly extending end of the ramification is preferably also somewhat reduced and is made to lap on the inner side of the downwardly disposed end 220i arm 20, to which it is suitablysecured.

The construction shown provides a more or less skeleton housing ,which, however, possesses ample strength while at the same ti ne being comparatively light in weight; the topand bottom members being secured together at four Widely spaced apart points and a iirmly and rigidly held, supporting member or bottom provided; the top and bottom members being formed to receive the trunnionslof the drive ahddrivri elements ployed merely as terms of description and not as terms of limitation as modifications are possible without, however, departing from the spirit of my invention.
